Topic: crate-type="staticlib" is broken for linux?

Luca Barbato (Dec 08 2018 at 15:22, on Zulip):

I tried currently with the stable build and the .a produced seems bogus, on macos it works as intended, anybody willing to point me where I should look at?

Seems good to me. Are you complaining about offset being shown as 0?

Luca Barbato (Dec 08 2018 at 18:15, on Zulip):

the linker complains

nagisa (Dec 08 2018 at 18:18, on Zulip):

complains how? Are you sure you pass your libraries to the linker in the right order?

Luca Barbato (Dec 08 2018 at 18:18, on Zulip):

I'm sure, the same code on macos works

Luca Barbato (Dec 08 2018 at 18:19, on Zulip):

switching from staticlib to cdylib works as well

Luca Barbato (Dec 08 2018 at 18:20, on Zulip):

it is only 1 library and the linker complains only about those symbols

Luca Barbato (Dec 08 2018 at 18:23, on Zulip):

dropping lto seems to fix it

nagisa (Dec 08 2018 at 18:27, on Zulip):

using LTO would explain it, as the static library would get filled with LLVM bytecode rather than actual machine code

nagisa (Dec 08 2018 at 18:27, on Zulip):

but the code’s there nevertheless

Luca Barbato (Dec 08 2018 at 18:37, on Zulip):

and the linker in use would not use it ^^;

Luca Barbato (Dec 08 2018 at 18:37, on Zulip):

let see if travis now is happy and I can go back chasing other funny bugs ^^

Luca Barbato (Dec 10 2018 at 10:32, on Zulip):

This is getting quite strange, I cannot it to link again and the lto is still off...

Luca Barbato (Dec 10 2018 at 11:50, on Zulip):

if somebody is willing to try here is the code ^^, make examples should take care of everything

Luca Barbato (Dec 10 2018 at 12:02, on Zulip):

maybe --print native-static-libs is the problem...

Luca Barbato (Dec 10 2018 at 12:02, on Zulip):

no apparently not
